I got a tiny sample at a store and thought maybe it would work. So I went home and followed the directions as stated and applied it on the area of pain. I was surprised that when I put the white cream on, it was cold. I mean, cold makes cramps hurt more. But I gave it some time and after 5 minutes, my cramp was worse. A LOT worse, that it hurt to stand up straight. I tried to rinse it off, but I guess it got absorbed by my skin, because it still felt super cold. The pain stayed for a while. I do not recommend this product. Rather drink hot chamomile tea or use hot compresses, but certainly not this cold product.
